Two independent research teams have discovered matching underground structures beneath Egypt's Giza plateau, extending over 1.2 kilometers deep - deeper than three Empire State Buildings stacked. In this groundbreaking investigation, satellite radar physicist Filippo Biondi and field researcher Trevor Grassi reveal how their completely different methodologies independently verified the same massive underground network beneath the pyramids and Sphinx. MAJOR REVELATIONS:

• Synthetic aperture radar (SAR) technology detecting structures 1,200 meters deep
• Independent confirmation from ground-penetrating radar matching satellite findings
• Three different satellite systems showing identical features
• Spiral shafts descending over a kilometer beneath the plateau
• Why Zahi Hawass withdrew from the Dubai conference
• The physics behind "space-based vibrometry" explained by former F-16 pilot

GUESTS:

• Filippo Biondi - Satellite radar physicist with 30+ years experience
• Trevor Grassi - Field researcher with 20 years at Giza
